Study Shows Blueberry Ingredient Reduces Blood Pressure

September 20, 2012: 12:00 AM EST
A randomized, placebo-controlled clinical trial involving 80 adults with high cholesterol showed that a commercial form of pterostilbene, a compound found naturally in blueberries, reduces blood pressure. The U.S. study evaluated whether the ingredient – marketed as pTeroPure – improves cardiovascular health. Participants took either high (125 mg) doses of pterostilbene, low doses, pterostilbene with grape extract or a placebo twice a day for 6-8 weeks. Patients who received the high doses of pterostilbene experienced significant drops in systolic and diastolic blood pressure, compared to the placebo group.
